A thermistor which is in contact with the heater roller regulates the temperature of the heater roller to a
designated temperature in the menu, depending on the thickness of the paper (tray 1&2: light=165°C,
medium light=170°C, medium=175°C, medium heavy and heavy=195°C/ manual feeding and power
envelope feeder: light=175°C, medium light=180°C, medium=185°C, medium heavy=190°C,
heavy=195°C). A safety thermostat cuts voltage supply to the heater off by opening the thermostat in the
event of abnormal temperature rises.
The back-up roller is held under a pressure of 7.52 kg applied by the pressure spring on each side.
(7) Cleaning
When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller
temporarily by static electricity, and the image drum surface is cleaned.
(8) Cleaning of rollers
The charge, transfer and cleaning rollers are cleaned for the following cases:
- Warming up when the power is turned on.
- Warming up after the opening and closing of the cover.
- When the number of sheets accumulated reaches 10 or more, and the printout operation ends.
Changes in bias voltage applied to each roller move the attaching toner off the roller to the image drum
and return it to the developer.
